Application filed .IunelO, 1903. Serial No. 160,881; (No model.)

, i e it known that I, FRANKR. GooDE,

zenof the United States, residing at Decatur,

in the county of Macon and State of Illinois, have invented certain new and useful Improvements in Draft-Equalizers, of which the followingis a specification, reference. being had therein to the accompanying drawings.

This invention relates to an improvement in spring-whiflietrees, and more particularly to an attachmentwhich can be used in connection with theflhammer strap. on the wagontongue now in use to convert. an ordinary whif whiflietree the ends of the spring are adapted fletree into a spring-whilfletree.

Inthe drawings accompanying the specification, wherein a preferable embodiment of myinvention is shownandin which like numerals of reference refer to similar parts in the several views, Figure l is a perspective View of my improved sprmg-whiffietree secured upon the tongue. Fig. 2 is a detail view of the spring. Fig. 3 is a detail View of one of the clips on the whiflietree. tail view of the. strap used to lengthen the hammer-strap; and Fig. 5' is a section on the line 1 1, Fig. 1.

Referring now more particularly to the drawings, A is a wagon-tongue ofv the ordinary construction having the usual hammer-strap B secured thereon.

C is a whifiletree arranged to slide between the hammer-strap and the tongue.

D is a bow-shaped spring arranged to be secured to the tongue in front of the whiffletree and against which the draft of the whiffletree is applied. The spring D has secured at a point intermediate its ends the U-shaped staple d, through which a bolt F passes to pivotally secure the spring to the tongue...

As the hammer-straps in use are too short to admit of use with my attachment, I have pro vided an extension therefor. This extension consists of a strap Gr, formed at its rear end with the aperture and at its forward end with the upwardly-extending hooked portion g. In use the hooked portion 9 is adapted to be inserted from beneath through the hole 6 in the end of the hammer-strap B, so that the flat top of the hooked portion will rest upon Fig. 4 is a dethe hammer-strap. The rear portion =of' the strap G is adapted to rest on the springD with the hole small 9 in alinement with the =U-shaped staple small d. The bolt F is then. passed through the'hole g, the-staple, and the tongueA.

The ends of the bow-shaped spring D are held in engagement with the forward-edge of the whiflietreeby means of the clips E.- These clips consist of two strips of metal a a, secured to the top and bottom of thewhifiietree'by the bolts 6 e and projecting over its forward edge.

J ournaled in the projecting ends of the clips E are friction-rollers f, between which and the to slide when a pull is exerted upon the whif- Wear plates at are secured to the front edge of the whifiietree immediately besaid spring from slipping from behind the clips E. Secured to the forward edge of the whiffietree and immediately behind the staple 'dof the spring is a coiled spring F, which is adapted to come in contact with the rear edge of the spring and act as a buffer when any very strong or sudden pull is exerted upon the whiffletree.

When constructing my springwhiflietree for the first time and not as an attachment for old wagon-tongues, I would dispense with the strap G and use instead a hammer-strap of sufficient length to hold the whifiietree and the spring.

I do not desire to limit myself to the precise form and construction shown in the drawings, as it is obvious that many minor changes might be made thereto without departing from the spirit of the invention.

What I claim is- 1. A device of the character described,'comprising a tongue, a hammer -strap secured thereon, a whiflietree arranged to slide between said hammer-strap and tongue, a bowspring having its central portion secured to the tongue and its end portions bearing against the whiffletree, and a coil-spring interposed between the spring and the adjacent side of the whiffletree.

2. A device of the character described, comprising a tongue, a hammerstrap secured thereon, a whiflietree arranged to slide between said hammer-strap and tongue, a bowspring having its central portion secured-to" the tongue and its end portions bearing. against.

the whiffletree, and a coil-spring secured to'the side of the whifiietree adjacent the spring.

3. A device of the character described, comprising a tongue, a hammer-strap secured. thereon, a whiflletree arranged to slide between said hammer-strap and tongue, a bow spring having its central portion secured to a 4. A device of the character described comprising a-tongue, a hammer-strap secured at one end to thetongue and having an aperture in its free end, a bow-spring having its ends arranged to bear against the whififletree and provided at its center with a U-shaped staple, and a bolt arranged to pass through the aperture in the hammer-strap, the staple on the spring and the tongue.

5. A device ofthe character described comprising a tongue, a hammer-strap secured at one end to the tongue and having an aperture in its free end, an extension-strap provided at one end'with a hooked portion adapted to engage the aperture in the free end of the hammer-strap and at the other end with an aperture, a bow-spring having its ends arranged to bear against the whifiletree and provided at its center with a U-shaped staple, and'a bolt arranged to pass through the aperture in the extension-strap, the staple on the spring and the-tongue.

6. A device of the character described comprising a tongue, a hammer-strap secured at one end to the tongue, an extension-strap secured to the free end of the hammer-strap, a bow-spring having its ends arranged'to bear against the whifiietree, and a pivot-bolt arranged to pass through the free end of the extension-strap, the spring at a point intermediate its ends and the tongue.

' 7 A device of the character described comprising a-tongue, a hammer-strap secured at one end to the tongue, an extension-strap secured to the free end of the hammer-strap, a bow spring having ends arranged to bear against the whiflietree, a pivot-bolt arranged to pass through the free end of the extensionstrap, the spring and the tongue, and a bufier secured to the side of the whifiietree adjacent the spring.

8. A device of the character described comprising a tongue, a hammer-strap secured at one end to the tongue, an extension-strap secured to the free end of the hammer-strap, a bow-spring having its ends arranged to bear against the whiifietree, clips secured to the whiflietree and arranged to embrace the free ends of said spring, friction-rollers journaled in the ends ofsaid clips and arranged to bear against the outside of the spring, and a pivotbolt arranged to pass through the free end of the extension-strap, the spring and the tongue.

In testimony whereof I afiix my signature in presence of two witnesses.

FRANK R. GOODE.
